Get a mixed natural hedge 75% hawthorn/blackthorn and the remainder hazel, spindle, field maple, wild cherry, wild plum, dogwood etc........all "Bare Root". Did a trench one spade deep and a foot wide. Plant the whips on alternate sides of the hedge nine inches apart so five/seven per yard. Two year old whips should cost about 49p each/Three year old a tad more. Colour all year round, loads of birds and some squirrels to shoot!
